llama3.1-8b-reasoning-summarizer

This model is a fine-tuned version of meta-llama/Llama-3.1-8B-Instruct on the seacorn/news-summarizer-reasoner dataset. It achieves the following results on the evaluation set:

Loss: 1.1173

Intended uses & limitations

The model performs best in summarization tasks, specifically in English and maybe Chinese. The model provides reasoning ON/OFF via system prompt trigger, all instructions should be contained within the user prompt.

Reasoning off example:

json

messages = [
    {"role": "system", "content": "reasoning off"},
    {"role": "user", "content": "Summarize the following into 5 bullet points, each with 20 words max.\n\nMarch 28 (Reuters) -..."}
]

# output
- Elon Musk's xAI acquires X ...

Reasoning on example:

json

messages = [
    {"role": "system", "content": "reasoning on"},
    {"role": "user", "content": "Summarize the following into 5 bullet points, each with 20 words max.\n\nMarch 28 (Reuters) -..."}
]

# output
<think>
Okay, I need to summarize this article into 5 bullet points, each with a maximum of 20 words. ...
</think>
